It really varies from person to person whether you consider the AP-15 dead-silent. I'm sure I'd hear it over my other controller hooked fans, so I went with a pair of AP-14's instead.

My Yate Loon's take such a performance hit at lower volts, since I can't stand anything over 25dBA. The GT's are perfect for the job and I'll probably be replacing some case fans for them as well. First two coming in today.

I have a Typhoon 15 on my CPU cooler. It runs full speed and i cannot find a way to control it. Not from bios not from Speedfan.
I control an AUX fan from Speedfan, no problem. But no the Typhoon. Any idea?

You'll have to ask someone that has an Asus mb. I believe there are threads that address this. The GT is a voltage controlled fan.

The AP-15 I just plugged into the SYS_FAN2 header on my mb is running at 1048 rpm right now. That's because in BIOS I set my automatic fan control to Enabled, and set the mode to Voltage. Asus mb's have something similar, IIRC.

I was planning on getting 7-8 of the 1850rpm models but they just raised the price at koolertek... I still will order 2 92mm GTs tho, I hope the 2650rpm isn't too loud

Unless the increase is massive, they're still worth their money. They'll soon be gone for a while, just like ehume said. My local shop is permanently out of AP-14's until furter notice, with the 15's following soon.
